Geometrie et horlogiographie pratique. Par Jean Bullant, architecte de haut & puissant seigneur, Monseigneur le duc de Montmorency, pair, & connestable de France.
Geometrie et horlogiographie pratique is a 1599 Paris geometry and sundial-making treatise by the architect Jean Bullant, printed by the widow of Guillaume Cavellat for patrons in the service of the Montmorency family. Its figures are plain line diagrams of semicircles, right triangles with construction lines, and a set square, ruler and compass, with dotted guide lines and lettered points. A designer could take their clean, schematic geometry as a model for technical diagrams, measurement layouts, or instructional graphics.
